When using a switch to trigger the Dry Run function on an ATV630 series drive, is it necessary to configure the Low flow / high flow parameters?

Issue:
Customer is using the Dry Run function of the ATV630 series to stop the motor in case of loss of prime on the pump.  They are using a float switch to trigger this function when the water level drops too low.  They need to know if it is still necessary to configure the low flow/low speed and high flow/high speed paramters that are used to sense dry run when a switch is not used.

Product line:
ATV630 series drives.

Environment:
All models, All serial numbers.

Cause:
Available literature is vague in this area.

Resolution:
No, it is not necessary to configure the Dry Run sensing parmaters when the dry run function is being triggered by a switch.  The switch will directly trigger the function, the sensing parameters will not be considered in this mode.
